Cryptography principles of bitcoin and blockchain

1. bitcoin is a digital currency based on a specific algorithm. < blockquote >

bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:

first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed

2.

The price of a bitcoin soared from more than $20000 to $40000. This can not help but arouse my research interest, or simply understand what bitcoin is, what its mechanism looks like, and uncover its mystery. Therefore, after a simple search of some information and some understanding of the special currency, I sorted out the information on hand< (3) purpose: decentralize, rece risk

(3) only the central server can store and process data in the central network; Large amount of data storage; The central manager has great authority

all servers in the distributed network can store and process data, and each server has equal status, which can store more data and has higher security<
this is the general content of popular science. If you want to know more about it, you can take a look at Nakamoto's paper and the official popular science video below

3. At present, there are many such teams, and the blockchain is suitable for all walks of life, but before the early cooperation, we must pay attention to the team strength and effect. The baker chain blockchain that we understand has a good evaluation in the instry, good reputation and good performance in all aspects. The evaluation of the instry is quite high.

4. Now we can use blockchain technology to finance. In the early stage, we can package roadshows to attract angel investment. In the later stage, we can issue digital currency online transactions to finance in the trading market. The cycle is generally 1-3 months and the cost is low. At present, it is a very safe and convenient way to find blockchain teams with hard technology and rich channels.

5. 0.001 bitcoin, and how much RMB, is multiplied by the current price, for example, 17881, 1m bitcoin is equal to 17.881

6. Jinyu is rooted in Hong Kong and supervised by the Hong Kong Monetary Authority. It was established in New Zealand and obtained the license of registration and supervision of local financial service providers. It has a good reputation in the instry.

7. Bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it

8. 1. Blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain
2. The transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
3. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain.
